Nutrient management |
Nutrient
management is a system used by farmers in the management of the amount, form,
placement, and timing of the application of nutrients (whether as manure,
commercial fertilizer, or other form of nutrients) to plants. The purpose of
nutrient management is to supply plant nutrients for optimum forage and crop
yields, to minimize non point source pollution and contamination of groundwater,
and to maintain and, or improve the condition of soil. Plant nutrients, which
come primarily from chemical fertilizers, manure, and in some cases sewage
sludge, are essential for crop production. When applied in proper quantities
and at appropriate times, nutrients (especially nitrogen, phosphorus, and potassium)
help achieve optimum yields of crop. However, improper application of the nutrients
can cause water quality problems both locally and downstream nature.
Equipment used in nutrient management
Tractors
|
Tractor |
Are traction machines that provide mechanical,
hydraulic, and or electrical power to perform a wide range of crop production
and handling operations. Tractors are most often used to perform drawbar work as well as power take-off work. Rubber
tires, rubber belts, or steel tracks can be used to equipped tractor. A modern
farm tractor is almost equipped with a diesel engine.
Planters
|
Planter |
Are
implements used in the planting of row crops (typically in row spacing ranging
from 10 to 40 inches). Planters open a seed trench, meter seeds one at a time,
drop seeds into the seed trench, and cover the seed gently. Some planters can
cut through residues and till a small strip of soil in each row at the time of
planting. Planters can also perform the application of liquid
fertilizer, pesticides, and herbicides during planting. Planters come in
sizes as large as sixty feet wide.
Sprayers
|
Sprayer |
Are
implements or vehicles that are used in the application of liquid crop
chemicals, most often herbicides, and fertilizers. Sprayers typically
include a tank, pump, plumbing, valves, a boom, and nozzles. It can be mounted
on a tractor or other implement, pulled by a tractor, self-propelled, or can be
mounted on airplanes or helicopters.
Spreaders
|
Spreader |
Are
implements or vehicles that can be used in the application of dry crop
chemicals, in most cases fertilizers. Spreaders typically include a bed,
conveyor, and either a set of spinning disks to distribute material over a wide
area or a pneumatic system to push material through openings in a boom for
distribution on the ground. It can also be mounted on a tractor, pulled by a
tractor, self-propelled, as well as airplanes.
